x^3=x*x*x
so you have x=-2
That means y=5-(-2*-2*-2)
y=5-(-8) which gives y=13
Do this for every x and get the y
Answer:
y's go
13, 6, 5, 4, -3
Step-by-step explanation:
well so you have the equation y = 5 - x^3
you are given the x for all of them
y = 5 - (-2)^3
5 - (-8) = 13
y = 5 - 0^3
5 - 0 = 5
y = 5 - 1^3
5 - 1 = 4
y = 5 - 2^3
5 - 8 = -3

The value of the function when x=3 is approximately 18.83.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
Linear function is a function whose graph is a straight line
We are given that;
The function
Now,
we need to substitute x=3 into the function and simplify it. We get:

How many diagonals does a
rectangle have?
Answers
A rectangle has two pairs of opposite sides that are equal in length and four right angles.
To determine the number of diagonals a rectangle has, we need to consider that a diagonal connects any two non-adjacent vertices of a shape.
In a rectangle, there are four vertices. For each vertex, we can draw a diagonal to any of the other three vertices that are not adjacent. Since there are four vertices in total, we can draw a diagonal from each of the four vertices to three other vertices, resulting in a total of 4 * 3 = 12 diagonals.
However, we must keep in mind that each diagonal is counted twice since it connects two different vertices. Therefore, we need to divide the total count of diagonals by 2, giving us the final answer.
Hence, a rectangle has 12/2 = 6 diagonals.

A. 7 + 12i
B. 3 + 6i
C. 3 − 6i
D. 7 + 6i
Answers
The difference of the two complex numbers (5 + 3i) and (2 + 9i) is; 3 - 6i.
What is the difference of the two complex numbers (5 + 3i) and (2 + 9i)?It follows from the task content that the two difference of the two complex numbers (5 + 3i) and (2 + 9i) be determined.
Since the numbers given are; (5 + 3i) and (2 + 9i).
The difference can be mathematically as follows;
( 5 + 3i ) - ( 2 + 9i )
By the Distributive property; we have;
5 + 3i - 2 - 9i
Collect like terms so that we have;
= 5 - 2 + 3i - 9i
= 3 - 6i
On this note, the difference between the two complex numbers is; 3 - 6i.

Step-by-step explanation:
here are the approximate population of three countries, expressed in scientific notation: panama: 4 x 10^6 ; peru: 3.2 x 10^7 ; thailand: 7 x 10^7. Lin says that more than 20 times as many people live in thailand than in panama. Is this correct
Answers
Answer:
No, Lin assumption is wrong
Step-by-step explanation:
Given
Population of panama = 4 x 10^6
population of thailand = 7 x 10^7.
Taking their ratios
thailand/panama = 7x 10^7/4 x 10^6
thailand/panama = 7/4 * 10^7-6}
thailand/panama = 1.75 * 10^1
thailand/panama = 17.5
thailand = 17.5 * panama
Hence the amount of people in thailand is not up to 20times those in panama. Hence Lin assumption is wrong
Using proportions, it is found that the ratio is of 17.5, hence Lin is not correct.
What is a proportion?A proportion is a fraction of a total amount.
In this problem:
Thailand's population is of 7 x 10^7.Panama's population is of 4 x 10^6.The ratio between the populations is given by:
r = 7 x 10^7/(4 x 10^6) = 1.75 x 10^1 = 17.5.
The ratio is of 17.5, hence Lin is not correct.
